Title: Innovations by Shigeki Fujiwara
Introduction
Shigeki Fujiwara is a notable inventor based in Izumiootsu, Japan. He has made significant contributions to the field of technology, holding a total of three patents. His work primarily focuses on enhancing the efficiency and precision of various mechanical systems.
Latest Patents
One of Fujiwara's latest inventions is the power-assisted cart. This innovative cart features a wheeled platform designed to support a load. It includes driving wheels that, when activated, enable movement of the platform. The cart is equipped with a drive unit for powering the wheels and an operating unit, typically a handle, that allows users to apply an external force for movement. A force detector is integrated to measure the magnitude and direction of the applied force, allowing for a control system that generates an output proportional to the detected force.
Another significant patent is his precision drilling method. This method involves drilling a straight hole in a workpiece using a drill unit that is suspended by electromagnetic forces. The drill unit is supported by controllable restoring and damping elements, which allow for positional displacement to relieve pressure when the drill contacts the workpiece. Sensors monitor this displacement, and if the force exceeds a critical value, the support is adjusted to stabilize the drill unit and dampen vibrations. This technique ensures that straight holes can be drilled accurately without damaging the drill.
